“…The TMS320F28335 connects the improved EKF observer and process implementation on target DSP [45] for the hardware test. First, the observer is expressed in mathematical form through the CCS toolbox and then it is optimized via the processor and later is transferred to the hardware platform This step occurs in two parts:…”

“…Re-configurability of Digital Signal Processing (DSP) devices gives researchers the chance to test and validate a novel controller; which does not damage the actual system through co-simulation, also known as Rapid Control Prototyping (RCP). The present work uses the Code Composer Studio (CCS) environment [45] to establish and validate an adaptive Improved Extended Kalman Filter (IEKF) speed estimator based on a Real-Coded-Genetic Algorithm (RC-GA-EKF). The research work models the system to improve the direct rotor field-oriented or the vectorcontrolled speed sensorless induction motor.…”

This work presents an investigation on Improved Extended Kalman Filter (IEKF) performance for induction motor drive without a speed sensor. The performance of a direct sensorless vector-controlled system through simulation and experimental work is tested. The proposed observer focuses on estimating rotor flux and mechanical speed of rotor from the stationary axis components. Extended Kalman Filters' estimation performance depends on the system matrix's proper value (Q) and measurement error matrix (R). These matrices are assumed to be persistent and are calculated by the trial-and-error method. But, the operating environment affects these matrix values. They must be updated based on the prevailing operating conditions to get high speed and accurate estimates. The values of Q and R in the Improved EKF (IEKF) algorithm are obtained using the genetic algorithm. Besides, IEKF is incorporated to reduce in computational burden for real-time applications.

Implementing a Novel Hybrid Maximum Power Point Tracking Technique in DSP via Simulink/MATLAB under Partially Shaded Conditions

This paper presents a hybrid maximum power point tracking (MPPT) method to detect the global maximum power point (GMPP) under partially shaded conditions (PSCs), which have more complex characteristics with multiple peak power points. The hybrid method can track the GMPP when a partial shadow occurs either before or after acquiring the MPP under uniform conditions. When PS occurs after obtaining the MPP during uniform conditions, the new operating point should be specified by the modified linear function, which reduces the searching zone of the GMPP and has a significant effect on reducing the reaching time of the GMPP. Simultaneously, the possible MPPs are scanned and stored when shifting the operating point to a new reference voltage. Finally, after determining the possible location of the GMPP, the GMPP is obtained using the modified P&O. Conversely, when PS occurs before obtaining the MPP, the referenced MPP should be specified. Thus, after recognizing the possible location of the GMPP, the modified P&O can be used to obtain the GMPP. The simulation and experimental implementations for the proposed algorithm are performed with different scenarios of shadowing under different irradiations, which clearly indicate that the proposed method is robust and has a fast tracking speed. Moreover, this work presents the load sizing method for PSCs to avoid controller failure when detecting the GMPP. Additionally, in this paper, the user-friendly method for programming the digital signal processing (DSP) via Simulink/MATLAB is presented in detail.

This paper presents the general guidelines on developing a laboratory prototype Voltage Source Converter (VSC). One of the main possible reasons behind the limited hardware verification by postgraduate students, carrying out research in the area of power electronics and especially the VSCs, is the lack of knowledge and unavailability of proper tutorials and guidelines for developing hardware prototypes. In this paper, majority of the auxiliary circuits and modules which are required for building up a prototype VSC are introduced. Proper examples are provided at each stage to improve the effectiveness of the developed guideline. The main difficulties of the hardware experiments are mentioned and possible solutions and recommendations are presented throughout the paper. It is believed that this paper will highly benefit the postgraduate students at the early stages of their hardware experiments. Index Terms-Voltage Source Converter (VSC), Laboratory prototype, Printed Circuit Board (PCB), Printed Circuit Board Assembly (PCBA).
